MAX1487ESA+T - Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers

The MAX1487ESA+T from Maxim Integrated is a high-performance, low-power transceiver for RS-485 and RS-422 communication. This device is designed for bidirectional data communications on multipoint bus transmission lines. It is a part of the family of devices that includes the MAX1487E, MAX487E, MAX488E, MAX489E, MAX490E, MAX491E, and MAX1487E.

Featuring slew-rate-limited drivers, the MAX1487ESA+T minimizes electromagnetic interference (EMI) and reduces reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. This device also features a low-current shutdown mode, current limiting, and thermal shutdown for protection against fault conditions.

With its half-duplex communication capability, the MAX1487ESA+T allows for the control of the driver and receiver over a single conductor. The transceiver draws a very low supply current when unloaded or fully loaded but with disabled drivers. It operates from a single 5V supply, making it suitable for many applications in industrial, telecommunications, and commercial environments.

The MAX1487ESA+T is available in an 8-pin SOIC package and is specified for operation from -40°C to +85°C, making it reliable for use in harsh environments. The integrated thermal shutdown and short-circuit protection ensure long-term reliability and robust operation in the field.

Key features of the MAX1487ESA+T include:

• Low-power operation for energy-efficient designs
• Slew-rate-limited drivers for reduced EMI and signal reflections
• Half-duplex communication for simplified network topologies
• Thermal shutdown and short-circuit protection for enhanced durability
• Current limiting for improved protection against high current conditions
• Extended temperature range for use in various environments

Overall, the MAX1487ESA+T is a robust and reliable solution for designers looking to implement RS-485 or RS-422 communication in their systems, with the added benefits of low power consumption and enhanced safety features.
